"Obviously we've got the browser-based MMO Doctor Who: Worlds In Time, we have other plans for other platforms and formats and we'll be announcing those.

"But right now The Adventure Games have done a great job, and they've been done, we're now going to move forward with the The Eternity Clock and we'll continue to develop those plans as we go ahead."

Harris added that the BBC will continue to look into offering public service content for UK licence fee payers.

"The Adventure Games are actually done by the production team down in Cardiff, and there's a question about now BBC Worldwide is focusing and investing in these developments, that providing audience expansion and providing something that's going to hopefully broaden the Doctor Who audience," he explained.

"That's something we're going to pick up on in gaming for the foreseeable future, and the team down in Cardiff are going to concentrate on some other things - which I've seen some of their ideas they haven't announced yet - but there is going to be some cool things around that to continue developing what they do around public service, around audience expansion for the UK licence payers."
